At this time, the material is injected along the injection port 21 on the upper mold 19, so that the material is introduced to the diversion port 27, and the fixed pipe 2 is used to cool the die-cast part. Then, the upper mold 19 is slid out along the guide holes 18 on the lower mold 1.

So that during use, the water flow enters the inside of the moving pipe 3 from one end of the moving pipe 3 along the flow hole 5, and then flows out along the mounting hole 11 inside the fixed pipe 2. And during the moving process, the cooperation of the guide rod 13 and the first spring 14 with the sliding connection between the fixing plate 7 and the sliding rod 6 plays a buffering role, and the second spring 29 and the buffer plate 30 are used in combination to play a buffering role.
[0043] During use, the upper die 19 is manually slid and installed along the guide holes 18 on the lower die 1 by means of the guide posts 20, so as to complete the fitting process between the upper die 19 and the lower die 1. At this time, the material is injected along the injection port 21 on the upper die 19, so that the material is introduced to the diversion port 27, and the fixed pipe 2 is used to complete the cooling process of the die-cast part. Then, the upper die 19 is slid out along the guide holes 18 on the lower die 1. At this time, the cylinder 23 is manually activated to drive the moving plate 24 at the output end to move up and down, so as to drive the ejector block 25 to move up and down, thereby ejecting the die-cast part.
